PROGRAM CLOCK.

To. all 10/2 om it may concern:

Be it known that I, citizen of the United Belle Rose, in the parish State. of Louisiana, have useful Improvements in P which the following is a s This invention relates t signal devices and has f vision of a novel elcctri device associated with ring any number of bell the program 1 able.

An important ob system of this in conjunction wi clock, the 'essen being capable being engagea n schools,

PAUL CoNoiENNn, a States, residing at of Assumption and invented new and rogram Clocks, ot' pecification.

0 time controlled or its object the procally operated signal a clock whereby to s in accordance with olleges and other places wheresuch an arrangement is desirjectis the provision of a character which may be used th a common ordinary tial elements of my device of use as an attachment and ble upon a clock in a very simpl manner which will involve little expense in manufacture an system.

d installation of the Anotherobject is the provision of an apparatus of this character which is provided with a circuit ditions.

the invention consists in to be hereinafter cribed and claimed and illusaccon'ipanying drawings, in

metal rim C, while I.) and E represent the minute and hour hand respectively.

In carrying out my invention I provide a series of metal contacts 16 which are preferably soldered or otherwise secured to the rim C and which extend inwardly thereof. ruralternative.arrangement is that the pa per or enamel face of the dial be scraped or otherwise treated to leave bare spaces. The contacts 10 are intended to be mounted at regular intervals, say for instance five minutes apart, that is to say thirty degrees apart.

The minutehand of course with these contacts 10 and end'thereof is a wire or free end of which is journaled a roller 12 which will engage the successive contacts 10 as the hand moves during the running of the clock.

The hour hand E carries a similar arm orwire 13 upon which is journaled a roller 14. Secured upon the face of he clock in the path otthe hour hand is a ring 15 of insulating material which is preferably dove tailed in cross section and adjacent which is mounted a metallic ring Detachably en.- gag ed upon the ring 15 is a plurality of clips 17 constructed of metal and of such formation as to snap onto the ring 15 and be retained thereon owing to the peculiar shape thereof. The inside edge of each clip is formed with a tongue 18 which may he engaged by the fingers'or by some imple ment such as a screw driver or the like when it is desired to remove the clip from its nor mal position. lVhen these clips are in posi out of engagement tion they are ordinarily l6 and when any clip is co-operatcs secured upon the arm 11 upon the by which is engaged beneath the tongue 18 in contact with the ring 16. The clips or contact members 17 are arranged at such intervals as desired to correspond to the intervals between the contacts 10. For a five minute interval, twelve clips are required to s inserted in the space traveled over by the hour hand during one hour so that when the roller carried by the minute hand is in engagement with the proper one of the contacts 10 the roller carried by the hour hand will be in engagement with the proper one of the contact clips 17.

In connection with the above described clock arrangement, it is of course neces- V sary to provide-a battery or other suitunderstood that any desired may be used connected in parallel. 7

ing from the other terminalof; the bell is: the metal,

able source: of current which'hassone. terminal connected with the rim (l and which: has its other terminal connected with oneterminal of a bell 21, it being of course number of bells Lead a wire 22 which is connected with ring. 16. In the operation. it is-of. course apparent that when the connector clips19 are in place associated with the proper one or ones of the clips 17, and whenduring the running of the clock the hour hand reaches these connected clips 17 with the minute hand roller engaging the-successive contactslO, the circuit-will be closedthrough .the" hell or bells for energizing them and giving. the .desired signal. 7

From th foregoing description anda-a study of the drawings it will lee-apparent that structed and easily installed arrangement or attachment by. means of which an ordinary clock may be converted-intov an auto.-

matic electric signalling device for: control-' ling bells or other similar devices foriindi- .cating the different periods of lectures,

classes, etc., in schools, colleges and other institutions.

While I haveshown and'descri'bedthe preferred embodiment of the inventionit is of [course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of. the inivention or the scope of the subj oined claims.
